Thanks ur comments. I'm using tcpdum for debugging issues instead of ngrep. SER receives a REGISTER message and replys with 483, TOO MANY HOPS message. I'm using three alias ('cause I don't know the rigt one to be used): 1.2.3.4, domain.com and sip.domain.com The diagnostic of X-PRO relates the same as SER.

Especially look at what happens when the message leaves your ser destined for the next hop. (I assume that the first message reached ser?!) You may experience this ex. if aliases in your ser.conf have not been specified for all IP addresses/aliases of your server. Ser will then not recognize messages. If the message does not reach ser at all, look at X-Pros diagnostic log. Post the part related to DNS lookup. g-) ---- Original Message ---- From: Vitor Brasileiro To: serusers(a)lists.iptel.org Sent: Thursday, December 30, 2004 03:02 AM Subject: [Serusers] DNS > Hi list, > > I`m in trouble configuring DNS. > My SER was working fine.
